Bug 284352

Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.1 (4.7.1)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:

I have made keyboard shortcut to display all the desktops simultaneously. When I updated the configuration to have 3 rows instead of 2 and tested the results plasma crashed. Never happened again and now I have 3 rows, so it could perhaps be a coincidence.

The crash does not seem to be reproducible.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Aborted
